Background

Function：Catalyzes the final rate-limiting step of glycolysis by mediating the transfer of a phosphoryl group from phosphoenolpyruvate (PEP) to ADP, generating ATP (PubMed:15996096, PubMed:1854723, PubMed:20847263). The ratio between the highly active tetrameric form and nearly inactive dimeric form determines whether glucose carbons are channeled to biosynthetic processes or used for glycolytic ATP production (PubMed:15996096, PubMed:1854723, PubMed:20847263). The transition between the 2 forms contributes to the control of glycolysis and is important for tumor cell proliferation and survival (PubMed:15996096, PubMed:1854723, PubMed:20847263); Isoform specifically expressed during embryogenesis that has low pyruvate kinase activity by itself and requires allosteric activation by D-fructose 1,6-bisphosphate (FBP) for pyruvate kinase activity (PubMed:18337823, PubMed:20847263). In addition to its pyruvate kinase activity in the cytoplasm, also acts as a regulator of transcription in the nucleus by acting as a protein kinase (PubMed:18191611, PubMed:21620138, PubMed:22056988, PubMed:22306293, PubMed:22901803, PubMed:24120661). Translocates into the nucleus in response to various signals, such as EGF receptor activation, and homodimerizes, leading to its conversion into a protein threonine- and tyrosine-protein kinase (PubMed:22056988, PubMed:22306293, PubMed:22901803, PubMed:24120661, PubMed:26787900). Catalyzes phosphorylation of STAT3 at 'Tyr-705' and histone H3 at 'Thr-11' (H3T11ph), leading to activate transcription (PubMed:22306293, PubMed:22901803, PubMed:24120661). Its ability to activate transcription plays a role in cancer cells by promoting cell proliferation and promote tumorigenesis (PubMed:18337823, PubMed:22901803, PubMed:26787900). Promotes the expression of the immune checkpoint protein CD274 in BMAL1-deficient macrophages (By similarity). May also act as a translation regulator for a subset of mRNAs, independently of its pyruvate kinase activity: associates with subpools of endoplasmic reticulum-associated ribosomes, binds directly to the mRNAs translated at the endoplasmic reticulum and promotes translation of these endoplasmic reticulum-destined mRNAs (By similarity). Plays a role in caspase independent cell death of tumor cells (PubMed:17308100); Pyruvate kinase isoform expressed in adult tissues, which replaces isoform M2 after birth (PubMed:18337823). In contrast to isoform M2, has high pyruvate kinase activity by itself and does not require allosteric activation by D-fructose 1,6-bisphosphate (FBP) for activity (PubMed:20847263)

Subcellular Localization：Cytoplasm; Nucleus; Cytoplasm

Expression：
Tissue_specificity:It is specifically expressed in proliferating cells, such as embryonic stem cells, embryonic cancer cells, and cancer cells; it is expressed in adult tissues (PubMed:18337823) . It is not expressed in tumor cells (PubMed:18337823) .

Isoforms & Post-Translational Modification：P14618 has 3 isomers: P14618-1: 57937 Da (predicted); P14618-2: 58062 Da (predicted); P14618-3: 56273 Da (predicted).
ISGylated;Under hypoxia, hydroxylated by EGLN3;Acetylation at Lys-305 is stimulated by high glucose concentration, it decreases enzyme activity and promotes its lysosomal-dependent degradation via chaperone-mediated autophagy;Acetylated at Lys-433 by EP300, leading to impair phosphoenolpyruvate substrate-binding and promote its homodimerization and subsequent translocation to the nucleus (PubMed:24120661). Deacetylation at Lys-433 by SIRT6 promotes its nuclear export into the cytoplasm, leading to suppress its nuclear localization and oncogenic function (PubMed:26787900);S-nitrosylation at Cys-423 and Cys-424 inhibits homotetramerization and pyruvate kinase activity (PubMed:30487609). S-nitrosylation is indirectly inhibited by AKR1A1 which degrades S-nitroso-CoA, a cofactor required to S-nitrosylate proteins (PubMed:30487609);FGFR1-dependent tyrosine phosphorylation is reduced by interaction with TRIM35

Subunit：Monomer and homotetramer; exists as a monomer in the absence of D-fructose 1,6-bisphosphate (FBP), and reversibly associates to form a homotetramer in the presence of FBP (PubMed:15996096, PubMed:18298799, PubMed:18337815, PubMed:1854723, PubMed:23064226, PubMed:2813362). The monomeric form binds 3,3',5-triiodo-L-thyronine (T3) (PubMed:15996096). Tetramer formation induces pyruvate kinase activity (PubMed:15996096, PubMed:18298799, PubMed:18337815, PubMed:1854723, PubMed:23064226, PubMed:2813362). The tetrameric form has high affinity for the substrate and is associated within the glycolytic enzyme complex (PubMed:15996096, PubMed:18298799, PubMed:18337815, PubMed:1854723, PubMed:23064226, PubMed:2813362). FBP stimulates the formation of tetramers from dimers (PubMed:15996096, PubMed:18298799, PubMed:18337815, PubMed:1854723, PubMed:23064226, PubMed:2813362). Homodimer; exists in a dimeric form in tumor cells and the dimeric form has less affinity for the phosphoenolpyruvate substrate (PubMed:22306293, PubMed:24120661). The homodimer converts into a protein kinase (PubMed:22306293, PubMed:24120661). Interacts with HERC1, POU5F1 and PML (PubMed:12650930, PubMed:18191611). Interacts with EGLN3; the interaction hydroxylates PKM under hypoxia and enhances binding to HIF1A (PubMed:21483450, PubMed:21620138). Interacts with HIF1A; the interaction is enhanced by binding of EGLN3, promoting enhanced transcription activity under hypoxia (PubMed:21620138). Interacts with TRIM35; this interaction prevents FGFR1-dependent tyrosine phosphorylation (PubMed:25263439). Interacts with JMJD8 (PubMed:27199445). Interacts with TRAF4 (PubMed:32268273). Interacts with (phosphorylated) CTNNB1; leading to activate transcription (PubMed:22056988). Interacts with TSC22D2; the interaction results in reduced nuclear levels of PKM isoform M2, leading to repression of cyclin CCND1 transcription and reduced cell growth (PubMed:27573352)

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
